Brembo 2PD.9049AS GT-S Series Rear Big Brake Kit 380x28mm 2-Piece Drilled Rotors 4-Piston Black Calipers

The Brembo 2PD.9049AS GT-S Series Rear Big Brake Kit is a complete, race-inspired braking upgrade engineered for high-performance street and track driving. Featuring fixed 4-piston cast monobloc aluminum calipers paired with massive 380x28mm (15-inch) two-piece cross-drilled rotors, this kit delivers dramatically improved stopping power, pedal feel, and fade resistance over the factory braking system.

GT-S Series Caliper Technology:

• 4-Piston Cast Monobloc Construction: Machined from a single piece of aluminum for outstanding rigidity, minimized flex, and superior heat dissipation under extreme braking loads
• Black Hard Anodized Finish: Durable, corrosion-resistant coating engineered for longevity at high operating temperatures
• Differential Piston Bores: Eliminate pad taper wear for even, consistent pad contact across the rotor surface
• Dual Inner Piston Seals: Twin seal design with inner pressure seal and outer wiper seal prevents debris intrusion and protects brake fluid from contamination
• Racing-Style Engraved Brembo Logo in Red: Iconic motorsport aesthetic as seen on Brembo's competition products

Two-Piece Cross-Drilled Rotor Specifications:

• Diameter x Width: 380mm x 28mm (approximately 14.96 inches)
• Construction: Advanced high carbon alloy for superior thermal management and crack resistance
• Cross-Drilled Surface: Straight-through drillings help dissipate heat, evacuate brake dust and gases, and channel away water for consistent rotor-to-pad contact
• 48-Vane Curved Vented Design: Maximizes airflow through the rotor for outstanding cooling capacity
• Corrosion-Resistant Plating: Zinc coating protects the rotor hat and vanes from rust and environmental degradation
• Floating D-Bobbin Mounting with Anti-Rattle Spring: Allows thermal expansion while reducing noise and vibration

Complete Kit Includes:

• Rear 4-piston monobloc calipers (black hard anodized) — sold as a complete axle set
• 380x28mm two-piece cross-drilled rotors
• High-performance brake pads
• Mechanical parking/emergency brake calipers
• Brembo-engineered CNC billet caliper adapters
• All necessary mounting hardware and brake lines
• Pre-assembled for straightforward installation

Backed by Brembo's 2-Year Warranty, the GT-S Series kit is compatible with factory ABS and traction control systems, making it an ideal upgrade for club racers, track day enthusiasts, and performance drivers who demand consistent, reliable braking under the most demanding conditions.
